A nurse is providing teaching to a client following surgery to repair a detached retina of the left eye. Which of the following instructions should the nurse include in the teaching?

Choice A reason: Limiting potassium intake is dangerous with digoxin, as low potassium (hypokalemia) increases the risk of digoxin toxicity by enhancing drug binding to cardiac cells. Adequate potassium levels are critical for safe use, as digoxin affects cardiac contractility, making this instruction incorrect and potentially harmful.
Choice B reason: Repeating a digoxin dose if the child vomits within 1 hour is unsafe without medical consultation, as it risks overdose. Digoxin has a narrow therapeutic index, and toxicity can cause arrhythmias. Parents should contact the provider for guidance, making this instruction incorrect and dangerous.
Choice C reason: Adding digoxin to juice risks inaccurate dosing, as the child may not consume the full amount, leading to underdosing or toxicity if additional doses are given. Precise administration (e.g., via syringe) ensures correct dosing, critical for digoxin’s narrow therapeutic range, making this instruction inappropriate.
Choice D reason: Having the child drink water after digoxin ensures the dose is fully swallowed, preventing loss from spitting or incomplete ingestion. This supports accurate dosing, essential for digoxin’s safe use in heart failure, where it enhances cardiac output. This instruction is safe and effective, making it correct.

Choice A reason: Using gauze to cover an infant’s IV site obscures visualization, delaying detection of infiltration or infection. Transparent dressings are preferred, as infants’ small veins are prone to complications. Gauze increases risk by hiding signs like swelling, critical for early intervention in pediatric IV management.
Choice B reason: Monitoring an IV site every 8 hours is inadequate for infants, who need hourly checks due to small vein fragility and high infiltration risk. Frequent assessment detects complications like phlebitis or extravasation early, ensuring vascular integrity and preventing tissue damage in pediatric patients.
Choice C reason: Inserting an IV in the foot is less preferred, as scalp or hand veins are more accessible and stable in infants. Foot IVs risk dislodgement from movement and may impair circulation, increasing complications like tissue damage, making this a suboptimal choice for IV placement.
Choice D reason: A 24-gauge catheter is ideal for infants, as their small veins require smaller needles to minimize trauma and infiltration. This size ensures adequate fluid or medication delivery while reducing vascular damage, aligning with pediatric IV guidelines for safe and effective venous access.
